Product Description

Products Details

A grooved adaptor flange is a pipe fitting used in grooved piping systems to connect pipes, valves, or other equipment with flanged connections. This type of flange is designed with grooves on its mating surface, allowing for quick, secure connections using grooved couplings, washers, and bolts.

Here are general guidelines on how to use grooved adaptor flanges:

Prepare pipes and flanges:

Make sure the ends of the pipes you connect have proper grooves.
Inspect the groove adaptor flange to make sure it is clean, free of debris and in good condition.
Place the gasket:

Insert the gasket into the grooved surface of the flange. Gaskets help create a seal between the flange and the mating surface.
Align flanges:

Position the slotted adaptor flange onto the mating surface of the equipment or piping assembly.
Secure with bolts:

Pass the bolts through the bolt holes in the flange and tighten with nuts. Bolts and nuts secure the flange to the mating surface.
Tighten the connection:

Use the appropriate tools to tighten the bolts evenly to ensure a tight, even connection.
Check for leaks:

After installation, check the connections for signs of leaks. Pressure testing can be performed to ensure the integrity of the joint.
Follow manufacturer’s guidelines:

Always follow the manufacturer’s guidelines for the specific grooved adaptor flange being used.
Comply with any applicable industry standards and regulations.
Materials and connection standards:
The material of the grooved adaptor flange can vary depending on the application and is typically made of ductile iron, stainless steel, or other materials suitable for the intended use and environment. Specific materials and connection standards depend on the manufacturer and application. The following are some general standards that may apply:

Material standards:

ASTM A536: Standard Specification for Ductile Iron Castings
ASTM A182: Standard Specification for Forged or Rolled Alloy and Stainless Steel Pipe Flanges and Forged Fittings
Connection standards:

AWWA C606: Groove and Shoulder Joints for Ductile Iron Pipe and Fittings
ANSI/AWWA C111/A21.11: Rubber Gasket Joints for Ductile Iron Pressure Piping and Fittings
Be sure to refer to the manufacturer’s documentation for specific details about material composition, specifications, and installation guidelines. Additionally, local building codes and regulations should be followed to ensure compliance and safety.
